[0002] A combiner, also known as a combiner or multiplexer, is a communication device that is mainly used to combine signals from multiple frequency bands into one signal so that it can be transmitted through a single transmission system. It is widely used in wireless communication systems, especially in situations where multiple frequency band signals need to be processed simultaneously. The combiner is usually located at the transmitting end. It can combine RF signals from different transmitters into one signal and then send it to the antenna for transmission. The design of the combiner ensures that the signals at each port do not interfere with each other.

[0003] In practical applications, the combiner does not process the acquired signals and directly forwards them. However, in fact, for some similar signals, the transmission process can be simplified to a certain extent, thereby reducing the load of the combiner, increasing the transmission speed, etc. How to simplify the transmission process is the technical problem that the technical solution of the present invention aims to solve.

[0065] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0066] Figure 1 : is a flowchart of an antenna signal transmission method based on a combiner. In an embodiment of the present invention, a method for transmitting antenna signals based on a combiner is provided. The method includes:

[0067] Step S100: acquiring real-time signals from various signal sources based on antennas, extracting features of the real-time signals at regular intervals, and clustering the signal sources according to the features and the positions of the signal sources; the data acquisition frequency of all signal sources is the same;

[0068] The antenna is used to collect signals. The real-time signal of the signal source can be obtained through the circuit, and the features of the real-time signal can be extracted. The real-time signal is then compared. Combined with the position of the signal source, the signal source can be clustered and similar signal sources can be classified into one category. Among them, the data collection frequency of all signal sources is the same, that is, each signal source collects a real-time signal once at the same time.

[0069] It should be noted that the real-time signal is a signal that is continuously acquired, and the analysis value of premature signals is actually very small. Therefore, this application generally sets a time period, takes the characteristic time, takes the current moment as the end moment, and obtains all real-time signals before the time period as the analysis object.

[0070] Step S200: selecting a reference signal from each type of real-time signal, and simplifying other signals in the same type of real-time signal according to the reference signal to obtain simplified data;

[0071] After the clustering process is completed, each type of real-time signal is analyzed separately, and a benchmark is selected from each type of real-time signal, called the benchmark signal. Then, other real-time signals are simplified according to the benchmark signal, so that other real-time signals are simplified into some simplified data. After simplification, each type of real-time signal becomes a separate real-time signal and simplified data.

[0072] Step S300: converting the reference signal and simplified data in the same type of signal into an optical signal based on a combiner, and sending the optical signal to the target end;

[0073] The combiner is used at the transmitting end. Its function is to combine two or more RF signals sent from different transmitters into one RF signal and send it to the RF device transmitted by the antenna, while avoiding mutual influence between the signals of each port. Its function is actually to combine different signals into one signal, and then convert it into an optical signal for forwarding and sending it to the target end; when the target end receives the optical signal, it reversely converts the optical signal to obtain the original signal.

[0074] In the technical solution of the present invention, the working process of the combiner is actually simplified. For similar signals with large differences, or when the accuracy of the original signal needs to be guaranteed to prevent distortion, the original signal is retained and a conventional solution is used for combining and forwarding. When similar signals are similar enough and the accuracy of the signal is not too high, the combiner only needs to transmit a single reference signal and some simplified data.

[0075] Step S400: When the target end receives the optical signal, the optical signal is inversely converted to obtain a reference signal and simplified data, and other signals of the same type are restored according to the inverse process of the simplified data generation process;

[0076] When the target end receives the optical signal, the optical signal is inversely converted to restore the original signal. For the unsimplified signal, it can be directly inversely converted. For the simplified signal, it is necessary to restore the signal based on the simplified data combined with the reference signal. This is the inverse process of step S200. In fact, there will be some distortion in the inverse conversion process. It is only applicable to the situation where the signals of the same type are similar enough and the accuracy of the signal is not too high.

[0077] Figure 2 The first sub-process flowchart of the antenna signal transmission method based on a combiner is shown in FIG. 1 , wherein the steps of acquiring the real-time signal of each signal source based on the antenna, extracting the characteristics of the real-time signal at regular intervals, and clustering the signal source according to the characteristics and the position of the signal source include:

[0078] Step S101: establishing a signal transmission channel between the antenna and each signal source, and acquiring a real-time signal based on the signal transmission channel; each real-time signal contains a unique tag determined by the signal source;

[0079] Step S102: taking the current time as the end time, reading the real-time signal before the preset period to obtain a signal sequence; the signal sequence is a time domain sequence;

[0080] Step S103: for any two signal sequences, calculate the difference sequence of each signal sequence;

[0081] Step S104: comparing the differential sequences, calculating the degree of difference between the two signal sequences as the logical distance, obtaining the position of each signal source, calculating the spatial distance, and clustering the signal sources according to the logical distance and the spatial distance;

[0082] The calculation process of the difference sequence is:

[0083] Where A[i] is the i-th value in the difference sequence, B[i] is the i-th value in the corresponding signal sequence, B[i+1] is the i+1-th value in the corresponding signal sequence; N is the total number of elements in the sequence.

[0084] The above content limits the clustering process of signal sources. In fact, this is also the clustering process of real-time signals. After the signal sources are clustered, the real-time signals of the same type of signal sources are combined and transmitted as a whole.

[0085] A signal transmission channel is established between the antenna and each signal source, and the real-time signal of each signal source is continuously obtained with the help of the signal transmission channel. A label is set in the real-time signal to characterize which signal source generates the real-time signal; then, the current moment is taken as the end moment, and the real-time signal before the preset time period is read to obtain a time series, called a signal sequence, which is actually a subset of all real-time signals above; for any two signal sequences, the difference of each element is calculated in turn, and the difference is statistically calculated to obtain a difference sequence; the difference sequences corresponding to different signal sequences are compared to calculate the degree of difference, which is called the logical distance; the signal sources are clustered by combining the two parameters of logical distance and actual space distance, so that relatively similar signal sources can be classified into one category. Generally, the closer the logical distance is, the easier it is for the two signal sources to be classified into one category, and the closer the actual space distance is, the easier it is for the two signal sources to be classified into one category. The degree of influence of the logical distance on the classification process and the degree of influence of the actual space distance on the classification process are preset by the designer.

[0086] The generation process of the above difference sequence is very simple. The key point is the tail term. There is no next element in the tail term. When calculating the difference, just copy the previous value.

[0087] Furthermore, the step of comparing the differential sequence, calculating the degree of difference between the two signal sequences as a logical distance, obtaining the position of each signal source, calculating the spatial distance, and clustering the signal sources according to the logical distance and the spatial distance includes:

[0088] Subtract two difference sequences to obtain a difference sequence;

[0089] Take the absolute value of the difference sequence, calculate the mean of all absolute values, and calculate the distance between the two signal sequences according to the mean as the logical distance; wherein, when the mean is small enough or large enough, the smaller the distance is, the closer the mean is to the middle, and the larger the distance is;

[0090] The position of each signal source is obtained, the spatial distance is calculated, and the signal sources are clustered according to the logical distance and the spatial distance.

[0091] The above content provides a specific signal source clustering scheme. For the signal sequences of any two signal sources, the differential sequence of the signal sequences is calculated, and the two differential sequences are subtracted to obtain a difference sequence. The difference sequence represents the difference between the two signal sources. The mean of all differences in the two difference sequences is calculated, and then the logical distance is calculated. The relationship between the logical distance and the mean is that when the mean is too large or too small, it means that the values ​​in the differential sequences of the two signal sources are positively correlated or negatively correlated, and the corresponding signal sequences have similar change trends, and the logical distance is small. Correspondingly, if the mean is in a normal state, it means that the correlation between the values ​​in the differential sequences of the two signal sources is very poor. At this time, they do not have similar change trends, and the logical distance is large.

[0092] Finally, the signal sources can be clustered using logical distance and spatial distance as parameters; as for the specific clustering scheme, a distance-based clustering scheme can be adopted, including but not limited to K-Means algorithm, Canopy algorithm, AGANS algorithm and DIANA algorithm.

[0093] In the above content, the calculation process of logical distance is:

[0094] d = αF; Where d is the logical distance, α is the preset correction coefficient, F is the value determined by the mean, a and b are two preset thresholds, a<b, when E<a, it means the mean is small enough, when E>b, it means the mean is large enough; M=max{aE min , E max -b}, E min is the minimum value of the mean corresponding to the difference sequence, E max is the maximum value of the mean corresponding to the difference sequence.

[0095] The calculation process of the logical distance is to determine whether the mean belongs to the preset range (a, b). If it does, the calculated F will take the maximum value and be set to 1. If it does not, it will take a smaller value. The larger or smaller the mean, the smaller the value. After correction, it can be used as the logical distance.

[0096] Figure 3The second sub-process flowchart of the antenna signal transmission method based on a combiner is as follows: the step of selecting a reference signal from each type of real-time signal, simplifying other signals in the same type of real-time signal according to the reference signal, and obtaining simplified data includes:

[0097] Step S201: Select a reference signal from each type of real-time signal;

[0098] Step S202: querying the logical distance of other real-time signals of the same type except the reference signal;

[0099] Step S203: determining a data retention frequency according to the logical distance, and retaining a signal value based on the data retention frequency;

[0100] Step S204: Count the signal value to be retained and the unique label of the signal source corresponding to the real-time signal to obtain simplified data;

[0101] The data retention frequency is proportional to the logical distance.

[0102] After the clustering of the signal sources is completed, a signal is selected from each type of real-time signal as the benchmark signal. Then, for other real-time signals of the same type, the logical distance is queried. The logical distance represents the degree of correlation between another real-time signal and the current real-time signal. The smaller the logical distance, the higher the degree of correlation, and the data retention frequency can be lower. The data retention frequency is how long a signal value is retained. The lower the data retention frequency, the smaller the retained signal value. Finally, the retained signal value and the corresponding unique label of the signal source are statistically counted to obtain simplified data.

[0103] It should be noted that for the above process of retaining signal values, if the logical distance is greater than the preset distance threshold, the data retention frequency adopts the preset maximum value and retains all signal values. At this time, the signal is not simplified and the combining process of the combiner adopts the existing technology.

[0104] Figure 4 The third sub-flow diagram of the antenna signal transmission method based on the combiner, when the target end receives the optical signal, the optical signal is inversely converted to obtain the reference signal and simplified data, and the steps of restoring other signals of the same type according to the inverse process of the generation process of the simplified data include:

[0105] Step S401: When the target end receives the optical signal, the optical signal is inversely converted to obtain a reference signal and simplified data;

[0106] Step S402: for any simplified data, query the retained signal value, fit the retained signal value, and obtain the restored signal;

[0107] Step S403: query the unique label in the simplified data to determine the signal source corresponding to the restored signal.

[0108] When the real-time signal is converted into an optical signal and sent to the target end, the optical signal is reversely converted with the help of a combiner, and the reference signal and simplified data can be obtained again (including the unconverted real-time signal, and the original signal is directly obtained after reverse conversion, which belongs to the conventional scheme and will not be repeated in this application). For the simplified data, the retained signal value is queried, and the retained signal value is fitted to obtain the restored signal. The fitting process can make use of the change of the reference signal, so the simplified real-time signal is very similar to the change of the reference signal, and the fitting process is not difficult; further, the simplified data also contains a unique label representing the signal source, which is used to indicate which signal source the restored signal is the real-time signal of.

[0109] As a preferred embodiment of the technical solution of the present invention, the method further includes:

[0110] Using 5G antennas, the number of similar signal sources after clustering is set to 4, and the 4 5G antennas are combined into one optical signal based on the combiner, and then the optical signal is converted into 4 5G signals at the target end.

[0111] The present application limits the working process of the combiner so that the combiner only combines four signals. When combining four signals, at most four signals need to be combined. At this time, the differences between the four signals are relatively large (the logical distance is large). In more cases, three signals will be simplified into some signal values. At this time, the working process of the combiner is only a photoelectric conversion process, and the combining process is equivalent to being simplified.
